PrintService service = PrintServiceLookup.lookupDefaultPrintService();
services = PrintServiceLookup.lookupPrintServices(DocFlavor.INPUT_STREAM.GIF, null);
AttributeSet aset = new HashAttributeSet();
aset.add(new PrinterName("HP LaserJet", null));
services = PrintServiceLookup.lookupPrintServices(null, aset);
aset = new HashAttributeSet();
aset.add(ColorSupported.SUPPORTED);
services = PrintServiceLookup.lookupPrintServices(null, aset);
}
